MACHINE FOR OPERATING ON SHOE STOCK 'Filed oct. 24, 1918 i( ji l l oit the welt to assist the ii eltto' Vlie hat and increase its ilezibility. Y

.v-ifilthoiig'h the incising,r means hasy been hereinbe'fore described in connection withf aV string nailing machine. it is nevertheless recognized that its utility is not limited to use in connection with a inachinenofA thatV Vtype but it may bev used'in connection with machines of other types, particularly those which may be employed lor attaching` welts to other pieces ot shoe stock or in connection with the attachment of shoe parts other than Welts.

An importantifeature of the invention in Y relationto its incorporation in fastening insertiiip; machines resides in the provision of .ai trame upon which is mounted 'fasteninginserting mechanism carried by'a laterally Y Vmovable'head with which is alsoV associated means for making` incisionsin 'the Work during the insertion of astenings therein. Preferably, and as illustrated, the fastening in sertingi mechanism Vcomprises a driver'and an awl which are operated in directions'to engage the work and also to Jfeed the work.

'lhejii'icisingmeans is inreterably mountedV for sliding' movement on the awl bar and is operatori lirorn the driver bar in such amanner that whensuch bar is lowered to linsert a fastening' into the work, the inc'isingmeans is also operated to maireV an incision in the worlr adjacent to the point where the Jfastening,r is inserted. Q

Although the incisingr means has been herein described as associated with a fastening' inserting machine, nevertheless. such means may be used in machines other than 1fastening` inserting machines or may constitlile in itself a separate machine.

Moreover, although the invention is particnlarly intended tor operation on welts, it is` realized that either the inrentionpas whole or certain 'features thereojt may be usefully employed on work ot other kinds. Y I Other objects and 'features ot the invention will appear asthe description proceeds and will be pointed out in the appended claims.

rllhe machine in connection Ywith which the invention is herein shown comprises acolnmn 2 upon which is mounted a hired head .4 on the front end of which a head 6 issiipportedin such manner. as to be movable erally of the fitted head 4.? ln machines of the type illustrated, the movable head. is mounted' forV Vswinging movement between the fixed head 4 an'd'plates and 10 YsecuredV thereto.' Y Y The movable head 6 carries the` astening insert-ing mechanism and also the means tor making' incisions in the work lin which theY Y is upheld by a hornQO or other suitable work support. Upon completion Vof the movement f et the head 6 to the lett?A the awlis retracted from the work, andthe head 6 is swung back to the right thereby bringing :the driverrinto alinement with the Vopeningvr made inthe Vwork by theawl. Thereafter, the driver is .moved downwardly to elfectfthe driving of the i'iail'wh'ich meanwhilehas been severed by the Vknifefrom the nail string in the guide 111. Y Y The driver and aivl are guided in the'pas- 4sanos ot a throat 22 carried by the lower end' of the swingingV headA 61 'and movable thereonby the 'fastening-.inseiting Amechanism. and is formedV with an. elongated open-V ing 26 in `which the throat 22ni0ves The guard plate-filas 'further provided with def vices inwhich is fornieda passage QS adapted to receive the Vweltltov be operatcd'upon and to guide the Vsame beneath the throat 22 in Vpositirm tor the insertionVof'iastenings tlierein. The elements thus tait-described form in themselvesno part oit th'epresent" invention but are'set forth in the saidP-atent No. 1.401,24?, to which reference has heretoA tore been'made, 1

F or slitting Yor cuttinl the .inner edge of' the welt, when desired, an incisingfblade or cutter 30 is slidablyY mounted in the throat 22, being reciprocated therein b v a holder Vtherewith relatively tothe guard plate 2li. which positions the work during; oi'ierationV 31 sleeved on theawl bar 18 and provided at its upper end witli upper Aand lower spacedf'lugsV-or projections and V34 re lreferably,'and as-illustrated, 'the incisingblade is operated by connections with fuif the driver bar so as `to .coordinate its movements with those of said bar. Accordingly, a stud 37 extending outwardly from the driver bar is received in a cam shaped slot 38 of lever 40, the other end of which is operatively connected to the lugs 32 and 34 of the incising blade 30.l Y Y Such connections Acomprise a stud 42 mounted in a bracket 44 ,in turn carried by the swinginghead v The stud 42 serves as ajfulcrum orthe rlever which `at its lower end has formed therewith or secured thereto a bar V45 which is recessed to serve as a guideway Vfor a sliding member 48. The member 48 hasat its end a -boss 50 adapted .to `be interposed between the lugs 32 and 34 of .the ineising means, movement the member 48 .relative to the stud 42 be ing permitted by the slotrl in said member.

lli/hen thebar 48 hasY been moved te int-r0-V duce the boss 50 into the space between the lugs 32 and 34, the motions of. the lever 40 are communicated to the incising means;

W hen, however,' the member 48 has been sov moved as to withdraw the boss 50 from between the lugs 32 and 34, the `incising means is not operated since movement of the lever 40 about its ulcrum 42 as the driver movesup and down no longer aiiects the lugs 32 and 34 of the incising means. Y

Preferably, the operator is enabled to render the incising means operative or in operative at will. Accordingly, we provide manually controllable means for engaging or disengaging theV .boss V50 from the lugs 32 and 34, in the illustrated construction, such means comprises a lever 52 carried by the stud 42 and operable by a handle 54 to move its cam suraceG either into or out of engagement witlr'a stud, 4orthe'like, 58 projecting from the member Y 48` into the path of movement of .the cam lever. The member 48 is moved in a directionV opposite to that in which it is moved by the cam'lever 52 by -a 'spring 60. Referring'to Fig. 3, it will be seen that when the stud 58 et the member 48 engages with the upper part of the cam surface of the lever 52, the Yspring 60 is enabled to move the member 48 lar enough to the left to insert the boss 50 of Y said member between the lugs 32 and 34 of the incising means. lVhen,VY however, the

cam ,lever 52 is moved from the position' shown in Fig. 3 to that shown in Fig. l, the cam surface of the lever 52 operates against the stud 58 of memberl48 and with-l draws the boss 50 of said member'from between the lugs 32 and. 34, thus breaking the connection between the lever 4() and the incising means as `indicated in Fig. l. It is desirable that the inelsing means when free from the control of the'member 48 should occupy a certain normal'position. To this end a spring 62 is providedwhich normally thus .urges such means upwardly to a point determined by the engagement et the upper surface of the upper lug 32 with a part or the swinging head 6.

r)The formation of thelewer lug 34 et the incising' means less width than the upper .lug 32 renders it easy to engage or diseir' space betweeirthe lugs.

If the handle lever 54 is operated during' the movement of the blade 3G downwardly to withdraw the boss 50 'from between the lugs 32 and 34, the blade will ence cease to move downwards and will begin to more upwards under the impulse of the spring 62. When, on the other hand, the handle 54 's turned in a direction to occasion engage ment of the lbess 50 between the lugs 32 and 34 when the driver is at or near the eX- tremity of its downward movement, the boss will not at once move into the space between the lugs 32 and 34 inasmuch as in such position et the driver, the boss is alined with the lower lug 34 (see Fig. 2). As the driver rises, however, it turns the lever 40 about stud 42 until the boss is brought into alinement with the space between the lugs 32 and 34 whereupon the spring 60 thrusts the boss into such space, operatively connecting the ineising means with the lever 40.

rEhe mounting oii the cutter holder 3l upon the awl bar i8 insures the cutting ot the welt in positions which will not interfere with .the subsefpient attachment oil the welt to the shoe by the nails which are driven for this purpose. The distance 'from the awlto the cutter is less than, and is illustrated as approximately halt, the dis-- tance between' adiarent awl holes and thus the cuts are similarly spaced with respect to the nails when they are driven. This tormation oit the slits or incisions in the welt in predetermined relation to the positions at which the fastenings are inserted believed to be new with applicants and constitutes an important :feature et the `ncsent invention, whether the invent" -n is viewed troni its method or troni its machine aspect.
